S. 601 would prohibit federal judges, when setting prison sentences in criminal cases, from considering conduct for which defendants were acquitted, unless consideration of the conduct would reduce the sentence. Under current law, there are no limitations on the information federal judges can consider when imposing a sentence in a criminal case. Specifically, under the bill, judges would be barred from considering conduct for which a person was charged and adjudicated not guilty by a federal, state, or tribal court.
